It's been confirmed by a number of people over the weekend that the RAM in Apple's little desktop isn't upgradable. You can upgrade the hard drive—but in doing so you will void the warranty. Sorry.

It's perhaps not massively surprising. Apple hasn't been making products any easier to upgrade, and given the small computer is essentially a MacBook in a different box, we aren't too shocked. But the old Mac Mini was surprisingly easy to upgrade, so it's a shame that's had to change.

If you want more RAM, you'll have to either buy a higher-end model or a custom order with more RAM. Both, sadly and predictably, more expensive than adding the RAM yourself. [MacRumors]
